NCT ID NCT05890716
First seen Jan 11, 2026 · Last updated Jun 22, 2026 · Updated 24 times
Summary
This study is testing whether an AI program called Willem can analyze ECG recordings as accurately as a human cardiologist. Over 5,000 high-risk heart patients will have their ECGs reviewed by both the AI and a doctor. The goal is to see if the AI can detect dangerous heart rhythms early, which could help prevent serious events like cardiac arrest or sudden death.
